    The number of poles in the motor winding. The synchronous speed can be calculated as: n = f (2 / p) 60 (1) where. n = shaft rotation speed (rev/min, rpm) f = frequency of electrical power supply (Hz, cycles/sec, 1/s) p = number of poles. Note - an induction motor will never reach its synchronous speed. If it did - the rotor would appear to be stationary to the rotating stator field since it would rotate with the same speed.
